Re:
Keep it simple, something like, "Yes I know about it, the three of us have a consenting poly relationship." Keep in mind, some people will be unaccepting no matter how well you explain it, so again keep it simple, "I'm sorry if this upsets you, all I can say is it works for us." This is your life and you have a right to live it.
Some people will not believe that you are *truly* consenting. They will think that Kim is using you and that you are enabling it. All you can say is, "Thanks for your concern, I will consider it." The point is, don't let yourself be drawn into a long, drawn-out argument, or long-winded explanations. Keep your responses trimmed down to the essentials. It is understandable if someone is concerned about your well-being, but this is something that you have to figure out on your own. Reading and posting on this forum is part of how you figure it out on your own, so I encourage you to keep doing that. As far as I can tell, your consent is joyful and genuine, but ultimately it's up to you to decide if that's true. Take all things into consideration, and draw new conclusions as you go along.
"Side note: How to explain to friends and family when they see Kim and Greg out dating together?"
